If a metal rod has a density of 7.85 g/cm and a volume of 4 cm, then what is its mass?
Bond [772]

Answer:

<h3>The answer is 31.4 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of metal = 4 cm³

density = 7.85 g/cm³

The mass is

mass = 7.85 × 4

We have the final answer as

<h3>31.4 g</h3>

Hope this helps you

Find the number of moles of water that can be formed if you have 210 mol of hydrogen gas and 100 mol of oxygen gas.
liraira [26]
<span>200 moles The balanced equation for creating water from hydrogen and oxygen gas is 2H2 + O2 => 2H2O So for every mole of oxygen gas, you need two moles of hydrogen. So looking that the amount of oxygen and hydrogen you have, it's obvious that oxygen is the limiting reactant since 100 moles of oxygen will consume 200 moles of hydrogen. While 210 moles of hydrogen requires 105 moles of oxygen. Now for each mole of oxygen gas you use, you create 2 moles of water. So 100 mol * 2 = 200 mol So you can create 200 moles of water from the given amounts of reactants.</span>

In a laboratory, bunsen burner is used to increase the temperature of lime from 10 °C to 50 °C with the thermal energy of 80000
galina1969 [7]

Answer:

c = 100 J/g.°C

Explanation:

Given data:

Mass of lime = 20 g

Heat absorbed = 80,000 J

Initial temperature = 10°C

Final temperature = 50°C

Specific heat capacity of lime = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 50°C - 10°C

ΔT = 40°C

80,000 J = 20 g×c×40°C

80,000 J = 800°C×c

c = 80,000 J /800g.°C

c = 100 J/g.°C
