Answer:

a. .125 mol b. 7.25g

Explanation:

a. To get the moles multiply the volume by the molarity.

.5L*.25M=.125mol NaCl

b. The molar mass is provided so multiply the moles by the molar mass to get the amount of grams of nacl.

.125mol*58molar mass=7.25g nacl to make the solution

A piece of metal with a mass of 611 g is placed into a graduated cylinder that contains 25.1 mL of water rising the water level

djyliett [7]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 611 g

volume = final volume of water - initial volume of water

volume = 256.7 - 25.1 = 231.6 mL

The density of the metal is

$density = \frac{611}{231.6} \\ = 2.638169257...$

We have the final answer as

Hope this helps you
