The answer is 0.055508435061792.
We assume you are converting between moles H2O and gram.
You can view more details on each measurement unit:
molecular weight of H2O or grams
This compound is also known as Water or Dihydrogen Monoxide.
The SI base unit for amount of substance is the mole.
1 mole is equal to 1 moles H2O, or 18.01528 grams.

Answer:

given \\ moles \: of \: water  (n) = 4.0 \\ molarmass(mr) = 18 \\ from \\ n =  \frac{m}{mr}  \\ n \times mr = m \\ m = mr \times n \\ 18 \times 4.0 \\ 72g

How many grams of CH4 will be in a 500ml contain at STP?
ArbitrLikvidat [17]

Answer:

Mass = 0.32 g

Explanation:

Given data:

Mass of CH₄ = ?

Volume of CH₄ = 500 mL (500 mL× 1L/1000 mL= 0.5 L)

Temperature = 273 K

Pressure = 1 atm

Solution:

Volume of CH₄:

500 mL (500 mL× 1L/1000 mL= 0.5 L)

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

By putting values,

1 atm× 0.5 L = n×0.0821 atm.L/ mol.K  × 273 K

0.5 atm.L = n×22.4 atm.L/ mol

n = 0.5 atm.L / 22.4 atm.L/ mol

n = 0.02 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.02 mol × 16 g/mol

Mass = 0.32 g
