The atomic mass of the metal.(M) = 51 g/mol

<h3>Further explanation</h3>

Given

32% of oxygen

Required

the atomic mass of the metal.​

Solution

An oxide of trivalent metal : M₂O₃(Ar O = 16 g/mol)

The molar mass of metal oxide = 2M+16.3=2M+48

32% of oxygen, then :

32% x 2M+48 = 48

0.32(2M+48)=48

0.64M+15.36=48

0.64M=32.64

M=51

What material makes up ash and pumice?
slamgirl [31]

Pumice rocks are formed due to the air that is trapped in between the rocks, a body of magma spurting out with dissolved gas under pressure. As the magma cracks through the Earth’s surface, the sudden pressure drop causes the gas to come out of the solution. The flash of gas form the vent slices the magma and blows it out as a molten lather. The lather hastily solidifies as it flies into the air and falls back to Earth as pieces of pumice.

What is the SI unit of pressure and from what units is it derived
irga5000 [103]

The Pascal (symbol: Pa) is the SI derived unit of pressure. It is used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one Newton per square meter. It is named after the French polymath Blaise Pascal.

The Pascal (Pa) or kilo pascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch.
