What is the volume (in cm^ 3 ) of 1.2 moles of water vapor at rtp? calculate the mass of this water vapor.

Volume = 29400 cm³

Mass =  21.6 g

Explanation:

Given data:

Number of moles of water vapors = 1.2 mol

Mass of water vapor = ?

Volume of water vapors = ?

Solution:

Room temperature = 25 °C (25+273 = 298 K)

Room pressure = 1 atm

PV = nRT

V =  nRT/P

V = 1.2 mol × 0.0821 atm. K⁻¹. mol⁻¹ . L × 298 K/ 1 atm

V = 29.4 L

In cm³:

29.4 × 1000 = 29400 mL

mL = cm³

Mass of water vapors:

Mass = number of moles × molar mass

Mass = 1.2 mol × 18 g/mol

Mass =  21.6 g

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
