What is the mass, in grams, of 0.00948\,\text {mol}0.00948mol0, point, 00948, start text, m, o, l, end text of phosphoric acid?
ANEK [815]
Answer:
0.929g
Explanation:
The following were obtained from the question.
Number of mole of phosphoric acid (H3PO4) = 0.00948mol.
Mass of H3PO4 =?
The mass in grams of phosphoric acid (H3PO4) can be obtained as follow:
Number of mole of H3PO4 = 0.00948mol.
Molar Mass of H3PO4 = (3x1) + 31 + (16x4) = 3 + 31 + 64 = 98g/mol
Mass of H3PO4 =?
Mass = number of mole x molar Mass
Mass of H3PO4 = 0.00948 x 98
Mass of H3PO4 = 0.929g
After careful deliberation, I took the opportunity to find the answers for you.
Answers:
1) _2_Al + _6_HC2H3O2 ->_2_Al(C2H3O2)3 + _3_H2
3) _1_Fe + _2_HBr -> _1_H2 + _1_FeBr2
5) _2_NaOH + _1_ H2SO4 -> _1_Na2SO4 + _2_H2O
7) _2_N2O -> _2_N2 + _1_ O2
9) _1_P4O6 + _2_O2 -> _1_P4O10
11) _2_Mg + _2_CH3COOH -> _2_Mg(CH3COO)2 + _1_H2
13) _2_Al3 + _18_HCl -> _9_H2 + _6_AlCl3
15) _4_KOH + _2_H2SO4 -> _4_H2O + _2_K2SO4
17) _2_NH3 -> _1_N2 + _3_H2
19) _2_SO2 + _1_O2 -> _2_SO3
DONE! *breathes heavily* Alright, after like 30 minutes, these are the answers for your problem.
Hope this helps! :)
the false statements are a, and e (not sure about e but think a is false)
Explanation:
The deeper you drill, the older the rock.
the rock & sediments are estimated at 86 million years old. drilled to a depth of 8,000 ft.
Answer:
<h2>When heat are heated,the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy.If more molecules hit each other with enough energy to react, then the rate of reaction increases </h2>
