Answer: O 10.1 is your answer! Please mark me as brainlyest!?
You'll need Avogadro's number for this. NH3 has 1 Nitrogen and 2 Hydrogen. You'll multiply the molar mass of each times Avogadro's number. So:
molar mass N x 6.022x10^23 x 1 Nitrogen= total A
Molar mass H x 6.022x10^23 x 2 Hydrogen= total B
Add total A+B = your answer
I don't have a calculator or periodic table but if you plug in the numbers you'll get your answer. Hope it helps.

Answer:
Empirical formula of acid is = C₄H₄O
In order to find the molecular formula we must have molar mass of compound. Because,
Molecular formula = n × (empirical formula)
n = molar mass of compound / empirical formula mass
Explanation:
No. of gram atoms of carbon = 70.6 g /12 g/mol = 5.88 g atom
No. of gram atoms of hydrogen =5.89 g / 1.008 g/mol = 5.84 g atom
No. of gram atoms of oxygen = 23.5 g / 16 g/mol = 1.47 g atom
Atomic ratio:
C :H :O 5.88/ 1.47 : 5.84/ 1.47 : 1.47 /1.47
C :H :O 4 : 4 : 1
empirical formula of acid is = C₄H₄O
Molecular formula:
Molecular formula = n × (empirical formula)
n = molar mass of compound / empirical formula mass
empirical formula mass= 4 × 12 + 4 × 1.008 + 1 × 16
empirical formula mass= 48+ 4.032 +16 = 68.032
