Answer : The mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.
Explanation : Given,
Mass of orpiment = 5.0 g
As we know that the molar mass of 
is, 246.02 g/mol and the molar mass of As is, 75 g/mol.
As per the question, we conclude that:
As, 246.02 g of contains mass of arsenic = 75 g
So, 5.0 g of contains mass of arsenic = 
Thus, the mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.
To obtain more accurate values of the densities of the pennies:
- more trials can be conducted to reduces the effect of measurement errors
- more care should be taken in taken volume measurements by displacement of water to avoid splashing of water.
<h3>What is density of a substance?</h3>
The density of a substance is the ratio of the mass of the substance to the volume of that substance.
It is a measure of the compactness of the matter in a substance.
The densities of the pennies made before 1982 was 8.7 g/ml
The actual density of pennies made before 1982 is about 8.8 g/mL.
The densities of the pennies made after 1982 was 6.9 g/ml
The actual density of pennies made after 1982 is about 7.2 g/mL.
Due to several random and experimental errors, the values obtained from the experiment are not exactly the same with the accepted values.
To obtain more accurate values:
- more trials can be conducted to reduces the effect of measurement errors
- more care should be taken in taken volume measurements by displacement of water to avoid splashing of water.
In conclusion, the densities varied as as a result of random and experimental errors.

Bonding ionically with a group 7 non-metal
The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. In this case, the atomic number of the atom is 3 and the atomic mass is 7. Hence the element is Lithium, a metal
