Question

Допоможіть будь ласка не люблю цю хімію( Обчисліть в якій речовині SO2 чи SO3 масова частка сульфуру більша (цифри- індекс)

Answer 1

Глянь на формулу де менше кисню, там быльше сульфуру 
розрахунки:
Mr(SO2)-32+16*2=64 W%S=32/64*100%=50%
Mr*SO3)=32+16*3=80     W%S-32/80*100%=40%

Answer 2

SO2 and SO3 are both chemical compounds that contain sulfur. The mass fraction of sulfur in each compound can be calculated by considering the molar mass of sulfur and the molar mass of the compound.

The molar mass of sulfur (S) is approximately 32.06 g/mol.

1. Calculating the mass fraction of sulfur in SO2: - The molar mass of SO2 is approximately 64.06 g/mol (32.06 g/mol for sulfur + 2 * 16.00 g/mol for oxygen). - To calculate the mass fraction of sulfur in SO2, we divide the molar mass of sulfur by the molar mass of SO2 and multiply by 100%: Mass fraction of sulfur in SO2 = (32.06 g/mol / 64.06 g/mol) * 100% = 50% [[1]].

2. Calculating the mass fraction of sulfur in SO3: - The molar mass of SO3 is approximately 80.06 g/mol (32.06 g/mol for sulfur + 3 * 16.00 g/mol for oxygen). - To calculate the mass fraction of sulfur in SO3, we divide the molar mass of sulfur by the molar mass of SO3 and multiply by 100%: Mass fraction of sulfur in SO3 = (32.06 g/mol / 80.06 g/mol) * 100% = 40% [[2]].

Therefore, the mass fraction of sulfur is higher in SO2 (50%) compared to SO3 (40%).
