156. A solid metal sphere has a volume of 4.2 ft}. The mass
snow_tiger [21]

Answer:

The answer is

<h2>0.59 g/cm³</h2>

Explanation:

To find the density of the sphere we use the formula

<h2>Density \:  =  \frac{mass}{volume}</h2>

To find the density in g/cm³ first convert the mass into grams and the volume into cm³

For the mass we have

155 lb = 70306.82 g

For the volume

4.2 ft³ = 118930.76 cm³

Substitute the values into the above formula

That's

<h2>Density \:  =  \frac{70306.82  \: g}{118930.76  \: cm³}</h2>

We have the final answer as

<h3>Density = 0.59 g/cm³</h3>

Hope this helps you

What is the normality of a solution that contains 1.89g of h2c2o2 2h2oin 1---ml of solution?
garri49 [273]

First convert mass to number of moles. Molar mass of H2C2O2 • 2H2O = 94 / mol

1.89g / (94 g / mol) = .02 mol H2C2O2 • 2H2O

Then we divide by 0.1 L, or 100 mL, and we get a concentration of 0.2 M.

Since there are two positive ions (2 H+), therefore normality is:
