Answer to Question #241347 in General Chemistry for jan

Question

In a biochemical assay, a chemist needs to add 2.93 g of glucose to a reaction mixture. Calculate the volume in mL of a 1.35M glucose solution she should use for the addition.

Answer 1

Molar mass of glucose: 180.156 g/mol

Moles of glucose $=\frac{2.93}{180.159}=0.016 moles$

Volumes of glucose $=\frac{0.016}{1.35}=0.0119l= 11.9ml$
