Answer:
Explanation:
"Three hundred ten million, seven hundred sixty-three thousand, one hundred thirty-six".
A) 36.0 x 100 /2 = 1800 g Be
n = m / MM
stoichiometry 1:1
atomic mass of Be= 100 g/ mol
b) theoretical yield
Al4C3 + 12H2O = 4Al(OH)3↓ + 3CH4
Answer:
0.1546 gram/mL
Explanation:
9.65lb/ft^3 in gram/mL => 0.1546 gram/mL
1ft^3 in mL => 28,316.8466 mL
1lb in gram => 453.5924 gram
9.65*453.59 gram/28316.84 mL => 0.1546 gram/mL
Answer:
6.0 x 10^-1 g Fe
Explanation:
I might be in the wrong but hear me out:
Convert 0.85 g to mols of Fe2O3.
0.85 g x 1 mol/159.69=0.0053 mols Fe2O3.
Get moles of Fe (iron metal).
0.0053 mols Fe2O3 x 2 mol Fe/ 1 mol Fe2O3
= 1.0 x 10^-2 mols Fe
Convert moles to grams of Fe.
1.0 x 10^-2 mols of Fe x 55.85 grams Fe/ 1 mol Fe
= 6.0 x 10^-1
There should be only one sig fig. Hoped this helped.
