Wine is approximately 12% ethanol by volume. ethanol has a molar mass of 46.06 g/mol and a density of 0.789g/ml. How many moles of ethanol are present in a 750 ml of wine?

This reaction has a CO2 percent yield of 62.3% What will be the mass of CO2 EXPERIMENTALLY obtained when 44.5g O2 and 24.6g C2H5OH are reacted? Molar masses: C2H5OH...

You have 2 moles, so there are 2×6.022×1023 oxygen molecules

Number of moles of H2SO3=0.8875moles

Half-time T = 12,3 years. The age of a bottle t: T = - tln2/ln∆N -tln2 = Tln∆N t = Tln∆N/-ln2 = 12.3•ln(0,1)/-ln2 = 12.3•(-2.3) / -0.693 =40.82 years

ANSWER SHOUD BE "a".EXPLANATION ......Zn reacts with HCl and form ZnCl2 and H2 .Balance Reaction is Zn + 2HCl ----- ZnCl2 + H2 .When 10 mol of Zn react with...

The mass of ethanol is found according to the equation: m = ρ × V, where ρ – the density and V – the volume. Thus, m = 0.789 g/ml...

Solution:Heptanoic acid = C7H14O2Hydrogen gas = H2C7H14O2 → 7H2According to the scheme above: n(C7H14O2) = n(H2)/7Thus:(8.32 g C7H14O2) × (1 mol C7H14O2 / 130.182 g C7H14O2) × (7 mol H2...

n=m/M A. n = 7.85g / 56g/mol = 0.14 mol B. n = 0.00468g / 28.1 g/mol = 0.00017

0.5 mol I2 and 0.5 mol Cl- will not react with anything; 2 mol I- will react with one mol of Cl2 producing one mol of I2: 2I- + Cl2...
