Volume of the metal = change in volume reading
Volume = 37.4 - 33
Volume = 4.4 ml

Density = mass / volume
Density = 7.101 / 4.4
Density = 1.61 g/ml

A chemical change combining two elements results in?
Neporo4naja [7]

Answer:

When two distinct elements are chemically combined for example, chemical bonds form between their atoms, the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium and Chloride, which combine to form table salt.

What is the molar mass of a gas which has a density of 0.00249 g/mL at 20.0 degrees celcius and 744.0 mm Hg?
creativ13 [48]

61.24 is the molar mass of a gas which has a density of 0.00249 g/mL at 20.0 degrees celcius and 744.0 mm Hg.

Explanation:

given that:

density = 0.00249 g/ml (\frac{mass}{volume})  or 2.49 grams/litre

P = 744 mm Hg OR 0.978 atm

T = 20 Degrees or 293.15 Kelvin

R = 0.08206 Litre atm/mole K

molar mass =?

Formula used/

PV = nRT    equation 1

here n is number of moles:

n = \frac{mass}{atomic mass}

putting the value of n and value of density in the equation 1:

PV = \frac{mass}{molar mass} x RT

molar mass = \frac{mass}{volume} x \frac{RT}{P}

                    = density x \frac{RT}{P}

                     = \frac{2.49 x 0.08276 x 293.15}{0.978}

                     = 61.24 is the molar mass of the gas.
