The molecular weight of O2 and SO2 are 32 and 64 respectively. At 15°C and 150 mmHg pressure, 1L of O2 contains -N - molecules. The number of molecules in 2L of SO2 under the same conditions of temperature and pressure will be

Question

The molecular weight of O2 and SO2 are 32 and 64 respectively. At 15°C and 150 mmHg pressure, 1L of O2 contains -N - molecules. The number of molecules in 2L of SO2 under the same conditions of temperature and pressure will be (A) N/2 (B) N (C) 2 N (D) 4 N

Tardigrade Admin · Accepted Answer

According to Avogadro's law "equal volumes of all gases contain equal number of molecules under similar conditions of temperature and pressure.
Thus, if 1 L of one gas contains N molecules, 2 L of any gas under similar conditions will contain 2 N molecules.

Q. The molecular weight of O2​ and SO2​ are 32 and 64 respectively. At 15∘C and 150 mmHg pressure, 1L of O2​ contains -N - molecules. The number of molecules in 2L of SO2​ under the same conditions of temperature and pressure will be

N/2

N

2 N

4 N

According to Avogadro's law "equal volumes of all gases contain equal number of molecules under similar conditions of temperature and pressure. Thus, if 1 L of one gas contains N molecules, 2 L of any gas under similar conditions will contain 2 N molecules.

Q. The molecular weight of $O_{2}$ and $S O_{2}$ are 32 and 64 respectively. At $1 5^{\circ} C$ and 150 mmHg pressure, 1L of $O_{2}$ contains -N - molecules. The number of molecules in 2L of $S O_{2}$ under the same conditions of temperature and pressure will be

According to Avogadro's law "equal volumes of all gases contain equal number of molecules under similar conditions of temperature and pressure.
Thus, if 1 L of one gas contains N molecules, 2 L of any gas under similar conditions will contain 2 N molecules.
