78.5 mol of P4O10 contains how many mols of P?
one mole of P4O11 will give 4 moles of P atomd
this we can say from formula
78.5 moles will give 4 x 78.5
= 314 moles of P
63.5 mol of p4o10 contains how many moles of P
2S(s)+3O2(g)→2SO3(g) A. If a reaction vessel initially contains 7 molS and 9 mol O 2, how many moles of S will be in the reaction vessel once the reactants have reacted as much as possible? (Assume 100% actual yield.) B. How many moles of O2 will be in the reaction vessel once the reactants have reacted as much as possible? (Assume 100% actual yield.) Show all work and explain each step please!
se 3. If you found that you need 0.2943 mols of copper, how many grams of copper do you need the molar mass of copper from above!) Note that the three conversions you just did above can be strung together as shown below: 8 AgNO, → mols AgNO, → mols Cu — g Cu Imol AgNO, 1 mol Cu 63.55 g Cu 100.0 g AgNO3 169 89. ANO, 2 mol AgNO, Imol Cu

How many moles of product are formed when 0.500 moles of P4O10 reacts with 6.00 moles of H2O? P4O10 + 6 H2O →4 H3PO4
How many mols of I will we find in a sample of HI (hydrogen iodide) gas that occupies a hollow sphere with radius = 11 cm? Some values you may find helpful: 12 = 253.81 g/mol H = 1.01 g/mol d = 2.9 g/L V = (4/3)pi(r) give your numerical answer to two decimal places
How many mols of F will we find in a sample of HF (hydrogen fluoride) gas that occupies a hollow sphere with radius = 10 cm? Some values you may find helpful: F = 19.0 g/mol H = 1.01 g/mol d = 1.15 g/L V = (4/3)pi(r3) give your numerical answer to two decimal places
i need help on the second page:
"calculate how many mols of HCL you used based on the volume
and molarity of the HCL"
and
"enthalpy of reaction" parts
Part B Heat of Reaction for HCl(aq) + NaOH (aq) NaCl (aq) + so H20 (1) Volume of 1.0 M HCl (ml) so 100 23.3 Volume of 1.0 M NaOH (ml) Mass of Solution (8) use 1.00 g/ml Ti solution (temp of HCl just before reaction) T solution (highest temp obtained)...
If a 2L reaction vessel initially contains 2 mols of Hydrogen and 2 mols of Iodine, what will be the molar concentrations at equilibrium of all species? H2 (g) + I2 (g) --> 2HI (g) Kc = 50.5
