Staff Answer

To find the total mass of a solution, you’ll need to add the mass of the solute to the mass of the solvent. If you don’t know the mass of the solvent or the solute, you can calculate them if you know their density and volume.

Question

How do you calculate mass from weight?

Staff Answer

Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

Question

How can I find a mass from kilograms?

Community Answer

Kilograms is representative of the mass, so you don't need to do any conversions.

Question

Is volume able to be measured without water?

Community Answer

Yes. All you need is a way to measure your solid and the formula for the volume of that solid. There are many formulas for volume. For example, the volume of a rectangular prism is V = Length X Width X Height. Let's say you have a rectangular prism with a measured length of 5, width of 10, and height of 3. Multiply all of those numbers, and the volume would be 150 units cubed.

Question

How can I calculate mass when I'm given the temperature?

Community Answer

Temperature is a measure of the average kinetic energy, and average kinetic energy is represented by 3/2 x k x T where k is the Boltzmann Constant (1.380 x 10 ^ -23 J/K) and T is the absolute temperature in Kelvin. Kinetic energy (avg.) is also equal to 1/2 m v^2 where m is mass and v is velocity, so 3/2 kt = 1/2 mv^2. Therefore, 3/2kT = 1/2 mv^2. From here, you can substitute and find the mass of the object.

Question

How do I convert the mass of an object to minutes?

Community Answer

You can't. Units of weight and units of time are different things.

Question

What is the percentage by mass if 2.5g of salt is dissolved in 25.0g water?

Community Answer

Divide 2.5 by 25.0, arriving at 0.1. Then multiply 0.1 by 100 to get a percentage -- 10% -- and that's your answer. The percentage by mass of 2.5g of salt dissolved in 25.0g water is 10%.

Question

How do we measure mass without water and a weighing scale?

Community Answer

If you know the density of the object and the volume, then do the equation: density times volume equals mass.

Question

If I know the mass of an object that is inside of another object, how can I determine the mass of the outer object?

Community Answer

Subtract the mass of the inside object from the total mass of the two objects. If you don't have the latter information, there is no way of knowing.

Question

How do I calculate the mass when volume is not provided?

Community Answer

Let's say the figure is a cube and the length is 2. To find the volume, you would do (2*2)2+(2*2)2+(2*2)2=24.

Question

How do I convert kilograms to grams?

Community Answer

There are 100 grams in one kilogram, so multiply the number of kilograms by 100 to get the number of grams. To get the number of kilograms from grams, divide by 100.

Question

How do I find the mass of an object when I know the weight and velocity?

Community Answer

To find an object's mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons.

Question

What is the percentage of relative abundance of Boron-10 and Boron-11, if its average atomic mass is 10.804amu?

Community Answer

The atomic mass of boron is 10.81 u. And 10.81 u is a lot closer to 11u than it is to 10u, so there must be more of boron-11. Where u is the unit for atomic mass and x is the proportion of boron-10 out of the total boron abundance which is 100%. And thus the abundance of boron-11 is roughly 81%.
