Question

mass of 2.05 X 10 power 16 molecules of H2SO4

Answer 1

Answer:

therefore you need to convert 2.05 * 10^16 to moles. the molecular weight of h2so4 is= 2h+s+4o= (2 + 32 + 64) =98. this is rounded up, so just take 98.07 for a more accurate result. m=0.00000334 grams.

Answer 2

Answer:

The mass of $2.05$ × $10^{16}$ molecules of $H_{2}SO_{4}$  is $3.335$ × $10^{-6}$ g

Explanation:

We know that $H_{2}SO_{4}$ contains two atoms of hydrogen, one atom of sulfur, and four atoms of oxygen are present.

The molecular mass of $H_{2}SO_{4}$ = $2+ 32+ 64 = 98 g/mol$

That is one mole of $H_{2}SO_{4}$ has 98 g/mol

Avogadro number of molecule's total mass = 98

Mass of one molecule of $H_{2}SO_{4}$ = $\frac{98}{6.022*10^{23} } =1.627 * 10^{-22}$

Therefore, the mass of $2.05*10^{16}$ molecules of $H_{2}SO_{4}$ is  $3.335* 10^{-6}$ g
