Determine the weight of 4.5 gallons of water. 1 quart of water weighs 2.1 pounds

There are 4 quarts in 1 gallon

4 quarts * 4.5 gallons of water= 18 quarts

If 1 quart of water weighs 2.1 lbs, then multiply 18 * 2.1

The weight of 4.5 gallons of water is equal to 37.8 lbs

Brainliest answer please :)

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
