calculate the molar mass of compound if 0.742 mole of it has a mass of 135 g.
Answer (1)
SOLUTION:Step 1: List the given values.[tex]\begin{aligned} & \text{mass} = \text{135 g} \\ & \text{no. of moles} = \text{0.742 mol} \end{aligned}[/tex]Step 2: Calculate the molar mass[tex]\begin{aligned} \text{molar mass} & = \frac{\text{mass}}{\text{no. of moles}} \\ & = \frac{\text{135 g}}{\text{0.742 mol}} \\ & = \text{182 g/mol} \end{aligned}[/tex]Hence, the molar mass of compound is 182 g/mol if 0.742 mole of it has a mass of 135 g.
