A chermist weighs out 400.0 g of Ca How many moles of Ca is this?
ra1l [238]

Answer:

<h3>The answer is 0.1 mol</h3>

Explanation:

To find out the number of moles we use the formula

n =  \frac{m}{M}  \\

where

n is the number of moles

M is the molar mass

m is the mass of the substance

From the question

m = 400 g

M of Ca = 40 g/mol

We have

n =  \frac{40}{400}  =  \frac{1}{10}  \\

We have the final answer as

<h3>0.1 mol</h3>

Hope this helps you
