Answer:

Mass = 185.896 g

Explanation:

Given data:

Mass in gram = ?

Number of moles = 2.00 mol

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of cobalt (I) hydroxide =92.948 g/mol

by putting the values,

2.00 mol = Mass/92.948 g/mol

Mass = 2.00 mol × 92.948 g/mol

Mass = 185.896 g

How are magnetic objects able to be

Vadim26 [7]

Answer:

Explorations include static electricity, magnets, electromagnets and permanent magnets. Examples of cause and effect relationships could include how the distance between objects affects strength of the force and how the orientation of magnets affects the direction of the magnetic force.

Determine the molecular formula for the compound with a molar mass of 46.08 g/mol and the following percent compostion:

kramer

Answer:

$\large\boxed{\large\boxed{CH_6N_2}}$

Explanation:

1. First determine the empirical formula.

a) Base: 100 g of compound

mass atomic mass number of moles

g g/mol mol

C 26.06 12.011 26.06/12.011 = 2.17

H 13.13 1.008 13.13/1.008 = 13.03

N 60.81 14.007 60.81/14.007 = 4.34

b) Divide every number of moles by the smallest number: 2.17

mass number of moles proportion

C 2.17/2.17 1

H 13.03/2.17 6

N 4.34/2.17 2

c) Empirical formula

$CH_6N_2$

d) Mass of the empirical formula

$1\times 12.011g/mol6+6\times 1.008g/mol+2\times 14.007g/mol=46.07g/mol$

2. Molecular formula

Since the mass of one unit of the empirical formula is equal to the molar mass of the compound, the molecular formula is the same as the empirical formula:

$CH_6N_2$

A pumpkin has a volume of 10 cm and a mass of 8 g. what is the density of the pumpkin

cricket20 [7]

Answer: 0.8g/cm^3

Explanation:

In seeing your problem, I see an issue with your units for centimeter. The volume is in the third dimension, so we use cm^3 every single time for the volume. That way, we can arrive to the correct density (in g/cm^3)

Density = mass/volume and so

Density = 8g/10cm^3

= 0.8g/cm^3
