The answer is true because technology we develop today makes powerful medicine in which could help expand life spans. It also helps us cure diseases, injuries, or other life threatening causes.
Answer:
0.146 g
Explanation:
Given data:
Volume of solution = 100 mL
Molarity = 10 mM
Molecular formula = C₇NH₁₆O₂
Mass of C₇NH₁₆O₂ needed = ?
Solution:
First of all we will convert the mM into M and mL to litter.
Volume of solution = 100 mL
Volume of solution = 100 / 1000 = 0. 1 L
Molarity = 10 mM
Molarity = 10 / 1000 = 0.01 M
Molar mass of C₇NH₁₆O₂ = 146.21 g/mol
For 1M solution we dissolve 146.21 g/mol in one litter
For 0.01 M
146.21 g/mol × 0.01 mol/ L = 1.4624 g/L
while we have to make 0.1 L solution,
1.4624 g/L ×0.1 L = 0.146 g
