Discuss FOUR ways in which one's acceptance of responsibility can influence
andrew11 [14]

Answer:

being responsible is owing up to the possible

consequences of your decision whether it was right or wrong.

communication is a two way process in which there is a messenger and receiver

one of the ways by which a person could be responsible is by saying 'I'

in all the things he would say, instead of 'we'

for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.

here u r establishing ownership on the things you want to say to the person

How many total atoms are in 0.670 g of p2o5?
scoray [572]

The molecular formula for compound is  P_{2}O_{5} mass of compound is 0.670 g.

To calculate number of atoms first calculate number of moles in the compound as follows:

n=\frac{m}{M}

Molar mass of  P_{2}O_{5} is 283.886 g/mol, thus,

n=\frac{0.670 g}{283.886 g/mol}=0.00236 mol

Thus, number of mole of P_{2}O_{5} is 0.00236 mol.

From the molecular formula 1 mole of P_{2}O_{5} has 2 mol of P (phosphorus) and 5 mol of O (oxygen).

Thus, number of moles of P and O in 0.00236 mol of P_{2}O_{5} will be:

n_{P}=2\times 0.00236 mol=0.00472 mol

Similarly,

n_{O}=5\times 0.00236 mol=0.0118 mol

Now, in 1 mol of an element there are 6.023\times 10^{23} atoms.

Number of atoms of P will be:

N_{P}=0.00472\times 6.023\times 10^{23}=2.84\times 10^{21}atoms

Similarly, number of atoms of O will be:

N_{O}=0.0118\times 6.023\times 10^{23}=7.11\times 10^{21}atoms

Total number of atoms will be sum of number of atoms of P and O:

N_{Total}=N_{P}+N_{O}=2.84\times 10^{21}+7.11\times 10^{21}=9.95\times 10^{21} atoms

Therefore, total number of atoms in P_{2}O_{5} will be 9.95\times 10^{21} atoms.

What do you put in the calculator to get the molar mass of Mg3P2
olga55 [171]

Input the atomic masses of Mg and P to give 134.84g/mol

Explanation:

The molar mass of a substance (atom or molecule or compound) is the mass in grams of one mole of the substance:

When dealing with an element the molar mass is the relative atomic mass expressed as g/mol.

For compounds, you add the atomic masses of the component atoms and you sum up.

You simply input the atomic mass of 3 atoms of Mg and 2 atoms of P

Atomic mass of Mg = 24.3g/mol

                             P = 30.97g/mole

Molar mass of Mg₃P₂ = 3(24.3) + 2(30.97) = 134.84g/mol
