Please help me!!! 1. Convert 4mols H20 to grams?

а 72g
b 92g
c 83g
d 62g

2. Convert 4mols of H2O to atoms of H2O?

a 1.4 x 10^24 atoms H2O
b 4.1 x 10^24 atoms H2O
c 3.3 x 10^24 atoms H2O
d 2.4 x 10^24 atoms H2O

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
