Question

При приготовлении компота сироп готовится из расчета 30 г сахара на 160 г воды. чему равна массовая доля сахара в этом спирте

Answer 1

Масса раствора: 160+30=190г
W(сахара)=30/190=0,1579(15,79%)

Answer 2

Calculation of Sugar Mass Fraction in the Syrup

To calculate the mass fraction of sugar in the syrup used to make the compote, we need to know the mass of sugar and the mass of water used in the syrup. According to the given information, the syrup is prepared with a ratio of 30 grams of sugar to 160 grams of water.

To find the mass fraction of sugar, we can use the following formula:

Mass Fraction of Sugar = (Mass of Sugar / Total Mass of Solution) * 100

Let's calculate the mass fraction of sugar in the syrup:

Mass of Sugar = 30 grams

Mass of Water = 160 grams

Total Mass of Solution = Mass of Sugar + Mass of Water

Total Mass of Solution = 30 grams + 160 grams = 190 grams

Mass Fraction of Sugar = (30 grams / 190 grams) * 100

Mass Fraction of Sugar ≈ 15.79%

Therefore, the mass fraction of sugar in the syrup used to make the compote is approximately 15.79%.

Please note that the calculation assumes that the sugar dissolves completely in the water to form a homogeneous solution.
