How many moles are in 345g of Re
andre [41]

Answer:

The number of mole is 1.852moles

Explanation:

To calculate the number of mole, using the formula

n = m/Mm

n - number of mole

m - number of mass

Mm - number of molar mass

The molar mass of Re = 186.207

Then, n = 345g/ 186.207g/mol

n = 1.852mol

What mass of water can be obtained from 4.0 g of H2 and 16 g of O2?2 H2 + O2 ---> 2 H2O18 g36 g54 g9 g
SashulF [63]

Answer:

18 g is the mass produced by 4 g of H₂ and 16 g of O₂

Explanation:

The reaction is:

2H₂  +  O₂  →  2H₂O

So, let's find out the limiting reactant as we have both data from the reactants.

Mass / Molar mass = moles

4 g/ 2g/m = 2 moles H₂

16g / 32 g/m = 0.5 moles O₂

2 moles of hydrogen react with 1 mol of oxygen, but I have 0.5, so the O₂ is the limiting.

1 mol of O₂ produces 2 mol of water.

0.5 mol of O₂ produce  (0.5  .2)/1 = 1 mol of water.

1 mol of water weighs 18 grams.

What is the density of a substance with a mass of 37.5 g and a volume of 20L?
ra1l [238]

Answer:

<h2>1.88 g/L</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{37.5}{20}  =  \frac{15}{8}  \\  = 1.875

We have the final answer as

<h3>1.88 g/L</h3>

Hope this helps you

Determine the only possible 2 ion for which the following two conditions are both satisfied: The net ionic charge is one-tenth t
Nadusha1986 [10]

Explanation:

The answer is the Calcium ion. It satisfies the conditions of the question.

Condition 1

The net ionic charge is one-tenth the nuclear charge.

In the Calcium ion,  Ca²⁺. The nuclear charge in this ion is 20. The net ionic charge is 2.

2 / 20 = 1 / 10. So the net ionic charge is indeed one tenth of the nuclear charge.

Condition 2

The number of neutrons is four more than the number of electrons.

Mass Number of Ca²⁺ = 44

Atomic Number = 20

Neutrons =  Mass Number - Atomic Number = 44 -20 = 24

Number of electrons = 20 - 2 = 18

Since Number of Neutrons = 22, Number of electrons = 18. This condition also holds.

As an ion and as an isotope = Ca²⁺, Ca - 42
