<u>Answer:</u> The moles of rubidium bromide for the given amount is 0.61 moles

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

We are given:

Given mass of RbBr = 100 g

Molar mass of RbBr = 165.37 g/mol

Putting values in above equation, we get:

\text{Moles of RbBr}=\frac{100g}{165.37g/mol}=0.61mol

Hence, the moles of rubidium bromide for the given amount is 0.61 moles

Answer:

a) 0.61 mol

Explanation:

165.3718 g Rubidium Bromide = 1 mol

100 g  Rubidium Bromide =  1/165.3718  x   100

                                          =  0.61 mol

Determine a massa, em kg, de um material que está contida em um volume de 18L. Sabe-se que a densidade do material é de 0,9 g/cm
suter [353]
The question in English is "<span>Determine the mass, in kg, of a material that is contained in a volume of 18L. It is known that the material density is 0.9 g/cm 3"

Answer: 
</span>
We can use a simple equation to solve this problem. <span>
    d = m/v</span><span>

<span>Where </span>d <span>is the density, </span>m <span>is the mass and </span>v is the volume.

d = </span>0.9<span> g/cm³
m = ?
v = </span>18 L = 18 x 10³ cm³<span>

By applying the equation,
<span>    0.9 g/cm³ = m / </span></span>18 x 10³ cm³<span>
                  m = 0.9 g/cm³ x </span>18 x 10³ cm³<span> 
<span>                  </span>m = 16200 g
                  m = 16.2 kg

Hence, the mass of 18 L of material is 16.2 kg.</span>
