what is the molar mass of n2h4?\n1 mol n = 14.01 g n\n1 mol h = 1.008 g h\n1 mol n2h4 = ? g n2h4\nround your answer to two decimal places.
Answer
Explanation:
Step1: Calculate mass of nitrogen in $N_2H_4$
There are 2 moles of N in $N_2H_4$. Mass of N = 2×14.01 g = 28.02 g
Step2: Calculate mass of hydrogen in $N_2H_4$
There are 4 moles of H in $N_2H_4$. Mass of H = 4×1.008 g = 4.032 g
Step3: Calculate molar - mass of $N_2H_4$
Molar mass of $N_2H_4$= mass of N+mass of H = 28.02 g+4.032 g = 32.052 g Rounding to two decimal places, we get 32.05 g
Answer:
32.05
