When 2.50 grams of copper reacts with oxygen?
ycow [4]
 <span>Mass oxigen = 2.81 - 2.50 = 0.31 g 
Moles O = 0.31 g / 15.9994 g/mol =0.0194 

moles Cu = 2.50 g / 63.546 g/mol =0.0393 

we divide by the smallest number 
0.0194 / 0.0194 = 1 => O 
0.0393 / 0.0194 = 2 => Cu 
the formula is Cu2O ( Copper (I) oxide )

Molar mass (NH4)2SO4
Hoochie [10]

Answer:

<u>132.15</u>

Explanation:

Molar mass N = 14.00

Molar mass H = 1.01

Molar mass H4 = 1.01 x 4 = 4.04

Molar mass NH4 = 14.00 + 4.04 = 18.04

Molar mass (NH4)2 = 18.04 x 2 = 36.08

Molar mass S = 32.07

Molar mass O = 16.00

Molar mass O4 = 16.00 x 4 = 64.00

Molar mass SO4 = 32.07 + 64.00 = 96.07

Molar mass (NH4)2SO4 = 36.08 + 96.07 = <u>132.14</u>
