The number of atoms that are in 9.008 moles of carbon is
5.423 x 10^24 atoms
<u><em>calculation</em></u>
The number of atoms is calculated using the Avogadro's constant
That is According to Avogadro's 1 moles = 6.02 x 10^23 atoms
9.008 moles= ? atoms
by cross multiplication
= [(9.008 moles x 6.02 x 10^23 atoms) / 1 mole] = 5.423 x10^24 atoms
Answer: check explanation
Explanation:
In this question we are to find mass. In order to calculate the Mass, We need the values of two parameters, that is, the values given for the grade tow chain, and the value given for the mass per length.
Assuming the mass per length is 3 Kilogram per metre(kg/m) and the grade 70 tow chain length is 5 metre(m).
Therefore, the formula for calculating mass of the chain is given below;
Mass of the chain= mass per unit length(kg/m) × length ---------------------------------------------------------------------------------------------------------------------(1).
Mass of the chain= 3 kg/m × 5 m.
Mass of the chain= 15 kg.
Answer:
The answer is
<h2>877 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 19.3 g/cm³
volume = 44.9 cm³
The mass of the gold bar
mass = 19.3 × 44.9 = 866.57
We have the final answer as
<h3>877 g</h3>
