# Question #7ba14

##### 1 Answer

The answer is approximately

Since you start with a concentration of **1M**, let's assume you have **1 L** of solution. That means that you have

This means that you have a mass of

In order to determine its density, you must calculate the percent concentration by mass of the

You'd then turn to a density table like this one:

According to this, a **percent concentration by mass** corresponds to approximately **62.478 g**, relatively close to **58.5 g**, your value).
