# Mass of a solution that has a density of 0.775 g/mL

• cgregory5006
In summary, to find the mass of a solution with a density of 0.775 g/mL and a volume of 50.0 mL, you can rearrange the equation Density = mass / volume to isolate the mass variable. Then, you can plug in the given values to find the answer.

What is the mass of a solution that has a density of 0.775 g/mL and a volume of 50.0 mL?

I am not sure how to find the mass

Density = mass / volume

Rearrange the equation to solve for mass.

To be more explicit, you have two equations already and now Ygggdrasil has given you a third. You can combine these to find the answer you're seeking. When trying to solve something with equations it's helpful to write down what you know and what you are seeking. It helps clarify the process.

Known

$$Density = \frac{0.775 g}{mL}$$

$$Volume = 50.0 mL$$

$$Density = \frac{Mass}{Volume}$$

Seeking

The Mass

Method

Look at the equations you have and try to rearrange them to isolate the thing you want (mass) on one side of an equation. Do this without numbers at first. Just look at the variables first (density, mass, and volume).

1) Isolate the variable you are seeking (mass) using algebra
2) Plug in the values you have to find the answer

What do you get?

## 1. What is the formula for calculating the mass of a solution?

The formula for calculating the mass of a solution is mass = density x volume.

## 2. How do you convert density from g/mL to kg/m3?

To convert density from g/mL to kg/m3, you can multiply the density value by 1000.

## 3. What is the mass of a 500 mL solution with a density of 0.775 g/mL?

To find the mass of a 500 mL solution with a density of 0.775 g/mL, we can use the formula: mass = 0.775 g/mL x 500 mL, which gives us a mass of 387.5 grams.

## 4. Can the mass of a solution be negative?

No, the mass of a solution cannot be negative. Mass is a physical quantity that represents the amount of matter in an object or substance. It cannot have a negative value.

## 5. How does the density of a solution affect its mass?

The density of a solution is directly proportional to its mass. This means that as the density increases, the mass also increases. Similarly, as the density decreases, the mass also decreases.
