Answer: 19kpa

Explanation:

The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.

P total = P X + P Y

From the question above:

P total = P .nitrogen + P. oxygen

123.5kpa = 104.5kpa + P. Oxygen

P. Oxygen = 123.5kpa - 104.5kpa

= 19kpa

How many grams of glucose are needed to form 150g of ethanol?

Svetradugi [14.3K]

<span>1 mole glucose gives 2 moles of ethanol

moles of glucose in 2.4 kg = 2400 / 180.18 = 13.320 moles

so moles of ethanol produced = 2* 13.32 = 26.64 moles

weight of ethanol 26.64 * 46.07

=1227.30 gm or 1.23 Kg</span>
