Acube with edge = 1.00” of an unknown pure substance has a mas off 10.0 oz. what is the density of this substance in g/ml? in kg/l?

Answer 1) The density of the cube will be 17.30 g/mL

We know the edge that is 1 inch, we have to convert it into cc which will be;

1" = 16.38 cc and cc = mL

The given mass is in oz, we need to convert this as well in g;

10 oz = 283.495 g;

We have the formula as Mass = Density / Volume

Substituting the values; Density = (283.495 / 16.38) = 17.30 g/mL

So the density will be 17.30 g/mL

Answer 2) The density of cube will be 1.738 Kg/L

The same procedure of conversion would be done here,

Mass in Kg will be 0.02834 Kg and Volume will be 0.0163 L

On solving with the equation as Mass = Density /  Volume;

Density = (0.02834 / 0.0163) = 1.738 Kg/L

Hence, the density will be 1.738 Kg/L

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
