Question

If 200,4 g of water is mixed with 101.42 g of salt, the mass of the final solution

Answer 1

Answer:

C) 301.8

Explanation:

Hello!

In this case, since the solution is composed by water and salt, the total resulting mass comes up from adding the mixed mass of each one:

$m_{sol}=m_{w}+m_{salt}$

Thus, we plug in to obtain:

$m_{sol}=200.4g+101.42g\\\\m_{sol}=301.8g$

Therefore, the answer should be C) 301.8 as it has four significant figures.

Best regards!
