Answer:- Mass of the alloy is 2.8 kg.
Solution:- Mass of Cr in the alloy is 325 g and mass of Fe in the alloy is 2.5 kg. Mass of alloy would be the sum of masses of constituent metals.
Masses of the metals are not in the same units. So, we need to make the units equal. The want answer in kg so let's convert mass of Cr from g to kg.
Since, 1000 g = 1 kg
So, [tex]325g\frac{1kg}{1000g}[/tex]
= 0.325 kg
Mass of alloy = mass of Cr + mass of Fe
mass of alloy = 0.325 kg + 2.5 kg = 2.825 kg
If we consider significant figures then as per the rules, the answer should not have more than one decimal place.
So, 2.825 kg is round off to 2.8 kg and hence the mass of the alloy is 2.8 kg.
2.825kg is the total mass of the alloy in kilograms of chromium (Cr) and iron (Fe).
What is alloy?
Alloy is a metallic substance which can be formed by the combination of the two or more number of elements or compounds.
In the given alloy constituent elements are chromium and iron.
Mass of given constituents are:
Mass of chromium = 325grams = 0.325kg
Mass of iron = 2.5kg
Mass of alloy is calculated as:
Mass of alloy = mass of chromium + mass of iron
Mass of alloy = 0.325 + 2.5 = 2.825kg
Hence, total mass of alloy is 2.825kg.
