How many atoms are present in 4 molecules of naoh?

The approximate molar mass of NaOH is 40 g/mol. You have 4 g NaOH.

No. of moles of NaOH is given by

n=(Given mass)/(Molar mass)

= 4/40 = 0.1 mol

1 mol has 6.022 × 10^23 molecules.

Thus, 0.1 mol has 6.022 × 10^23 × 0.1 molecules i.e. 6.022 × 10^22 molecules.

Explanation:

14,16 18 reacts with group

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
