Answer:
10
Explanation:
you need to balance the reaction. the left must be equal to the fight hànd. multiply both sides by 2
Cause their are both have difference s
Answer:
334.08 g
Explanation:
87 proof = 43.5%
in 1L of liquid there is 43.5% alcohol/ethanol
1L (43.5/100) = 0.435 L alcohol
we want density in g/L because that's the volume u have
density 0.798 g/mL = 798 g/L
multiply the volume of alcohol by its density to get grams
0.435 L(798 g/L) = 334.08 g
Assuming ideal gas law applies to the problem, we find the pressure from the given volume, temperature and number of moles. The ideal gas equation is PV=nRT. R is 0.0821 L atm/ mol K. Substituting the data given, P= (2.50 moles)(0.0821 L atm/ mol K)(27+273 K)/(50 L)= 1.2315 atm. This is equivalent to 936 mm Hg.
