If a person consumes 50% of their daily kilocalories from carbohydrates and 30% from protein, what percentage of their daily kilocalories will come from fat?
Answers
The percentage of daily kilocalories of the person that come from fat is 20%.
The diet of a person is composed mainly of carbohydrates (C), proteins (P) and fat (F), that is, the sum of the 3 sources amount to 100% of the consumed kilocalories. Given that 50% of the daily kilocalories of this person come from carbohydrates and 30% come from protein, the percentage that comes from fats is:
[tex]C + P + F = 100\%\\F = 100\% - C - P\\F = 100\% - 50\% - 30\% = 20\%[/tex]
The percentage of daily kilocalories of the person that come from fat is 20%.

The compound XCl4 contains 75.0% Cl by mass. What is the
element X?
nch of the following
Answers
The element X is titanium.
According to the question, the percentage by mass of Cl in XCl4 is 75.0%.
The percentage by mass is obtained from;
Mass of element in the compound/molar mass of compound * 100
Hence;
Let the mass of the unknown element be X
75 = 142/X + 142 * 100
75 (X + 142) = 142 * 100
75X + 10650 = 14200
75X = 14200 - 10650
X = 14200 - 10650/75
X = 47
Hence, X is titanium.
