Question

60 грамм воды + 3 грамма хлороводорода найти W(HCl)

Answer 1

60 грамм воды + 3 грамма хлороводорода найти
W(HCl)= массу вещества поделить на массу раствора, находим массу раствора= масса в-ва+ массу воды=3+60=63 г
W(HCl)=3/63*100%=4,8%

Answer 2

Calculating the Mass of Hydrogen Chloride (HCl)

To find the mass of hydrogen chloride (HCl) in 60 grams of water and 3 grams of hydrogen chloride, we can use the following formula:

W(HCl) = (mass of HCl) / (molar mass of HCl)

Given: - Mass of water = 60 grams - Mass of hydrogen chloride = 3 grams

First, we need to calculate the molar mass of HCl, which is approximately 36.46 g/mol.

Now, we can use the formula to find the mass of hydrogen chloride: W(HCl) = 3 / 36.46 ≈ 0.0822 moles

Therefore, the mass of hydrogen chloride in the given mixture is approximately 0.0822 moles.
