a solution contains 4.92 g of sodium lithium chloride in 347 g of water. what is the weight % or percent by…

Explanation:

Step1: Identify solute and solution mass

Solute mass ($m_{solute}$) = 4.92 g, solution mass ($m_{solution}$)=$m_{solute}+m_{solvent}$ = 4.92 g+347 g = 351.92 g

Step2: Calculate mass - percent formula

The formula for mass - percent is $\text{Mass}%=\frac{m_{solute}}{m_{solution}}\times100%$. Substitute the values: $\text{Mass}%=\frac{4.92}{351.92}\times100%$

Step3: Perform the calculation

$\text{Mass}%=\frac{4.92}{351.92}\times100%\approx1.40%$

Answer:

1.40%
