Answer:
60g of LiNO3 are required
Explanation:
<em>Calculate the amount of solute, in grams or milliliters, to prepare...</em>
<em />
The percentage mass/volume %(m/v) is defined as the mass in grams of the solute in 100mL of solution
To solve this question we must know that in a 37.5% (m/v) of LiNO3 you have 37.5g of LiNO3 in 100mL of solution.
Thus, to prepare 160mL are required:
160mL * (37.5g / 100mL) =
<h3>60g of LiNO3 are required</h3>
