Chemistry
1 answer:
Aleks [24]3 years ago
6 0

Answer:

No. of moles, n = 7.52 moles

Explanation:

Given that,

Mass, m = 563.9 grams

Molar mass of arsenic = 74.92 g/mol

We need to find the number of moles in 563.9 grams of arsenic. Let it is denoted by n. It is equal to given mass divided by total molar mass.

n=\dfrac{563.9 }{74.92}\\\\=7.52\ \text{moles}

So, there are 7.52 moles in 563.9 grams of arsenic.

The bonds of four salts (MgBr2, NaCl, MgCl2, and NaBr) are evaluated for ionic character based on electronegativity differences
sammy [17]

Answer:

MgBr2 < MgCl2 < NaBr < NaCl

Explanation:

In order to determinate ionic character, we have to subtract the electronegativity from the elements involved. This is known as Pauling rule.

MgBr2 > ΔΕΝ = 1.8

NaCl > ΔΕΝ = 2.3

MgCl2 > ΔΕΝ = 2

NaBr > ΔΕΝ = 2.1

A rectangular container of air measures 1.2 x 10-2 m by 8.34 x 10 1 m by 6.0 x 10-1 m. Air
Dominik [7]

The volume of the rectangle has been given by the product of length, breadth, and height. The mass of the air with a density of 1180 g/m³ is 708.57 gms.

<h3>What is density?</h3>

The density of the substance has been known to be given by the mass's ratio to the volume. The formula for density is given as,

Density = Mass ÷ Volume

Given,

Density = 1180 g/m³

The volume of the rectangle = L×B×H

Substituting the values above,

Mass = Density × Volume

M = 1180 × 1.2 × 10⁻² × 8.34 × 10¹ × 6.0 × 10⁻¹

= 708.57 gm

Therefore, the mass of the air is 708.57 gms.
