A chermist weighs out 400.0 g of Ca How many moles of Ca is this?

ra1l [238]

Answer:

<h3>The answer is 0.1 mol</h3>

Explanation:

To find out the number of moles we use the formula

$n = \frac{m}{M} \\$

where

n is the number of moles

M is the molar mass

m is the mass of the substance

From the question

m = 400 g

M of Ca = 40 g/mol

We have

$n = \frac{40}{400} = \frac{1}{10} \\$

We have the final answer as

Hope this helps you

A student was provided with a solid sample made up of a mixture of components. Prior to separation, the student measured 2.895 g

Shtirlitz [24]

Answer:

Component 1, since it has the greatest mass.

Explanation:

Hello,

In this case, considering that the by-mass percent of a substance is computed:

$\% m/m_i=\frac{m_i}{m_{mixture}}*100\%$

In such a way, given the form of the equation one could infer that the higher the mass of the i component, the higher its by-mass percent, it means that the component with the greatest mass will have the highest by-mass percent for the mixture. In such a way, since the component 1 was found to have a mass of 1.12 g, it will have the highest by-mass percent.

Best regards.
