1 mole of calcium, one mole of carbon, and 3 moles of oxygen.
Explanation:
Answer:
0.045 moles of NaOH
Explanation:
When this units are together mol/L, we talk about M, molarity.
This kind of concentration shows the relation between moles of solute which are contained in 1L of solution.
In this case, our NaOH solution is 0.30 M
M = mol/L
Then, M . L = mol
We convert volume to L → 150 mL . 1L /1000 mL = 0.150L
0.150 L . 0.30mol/L = 0.045 moles

For a stationary fluid, the pressure will vary in the x, y and z directions.
Answer: molecular formula = C12H16O8
Explanation:
NB Mm CO2= 44g/mol
Mm H2O= 18g/mol
Moles of CO2 = 36.86/44=0.84mol
0.84mole of CO2 has 0.84 mol of C
Moles of H2O = 10.06/18= 0.56mol
1mol of H20 contains 1mol of O and 2 mol H,
Hence there are 0.56mol O and (0.56×2)mol H
Hence the compound contains
C= 0.84 mol H= 1.12mol O=0.56mol
Divide through by smallest number
C= 0.83/0.56= 1.5mol
H= 1.12/0.55= 2mol
O= 0.56/0.56= 1mol
Multiply all by 2 to have whole number of moles = 3:4:2
Hence empirical formula= C3H4O2
(C3H4O2)n = 288.38
[(12×3) + 4+(16×2)]n= 288.38
72n=288.38
n= 4
:. Molecular formula=(C3H4O2)4= C12H16O8
