when calculating density do you put the mass quainty in front of the volume ex: 95 g for Mass dived by 950 gives .1 ml for densi

denpristay [2]

It should be mass divided by volume correct?

Determine the number of lone pair electrons on each H in NH3. Z of N= 7, H=1 A. 0 B. 3 C. 1 D. 2

Darya [45]

Answer:

Option A. 0

Explanation:

To know the number of lone pair on each H in NH3, we shall determine how NH3 is formed. This is illustrated below:

3H + N —> NH3

Three atoms of Hydrogen, H reacted with 1 atom of nitrogen to produce ammonia, NH3. Each atoms contribute one electron each to form the covalent bond in NH3.

Hydrogen has only one electron and it will share it with the nitrogen atom to produce ammonia.

Further details can be seen in the attached photo.

Further more, in the attached photo, we can see that there is no lone pair of electron in the hydrogen atom as all it's electron has been used to form bond with the nitrogen atom. Only the nitrogen has a lone pair of electron.

Therefore, there are zero lone pair of electron on each hydrogen, H atom in ammonia, NH3.

How many grams of oxygen are in 50.00 g of sucrose? Show work please

Serga [27]

You need the molercular mass of Sucrose.

You can either search the molecular formula of Sucrose and calculate the molecular mass, or search directly the molecular mass.

Here you have both:

Molecular mass of sucrose: 342.30 g / mol

Chemical formula of sucrose: C12 H22 O11 (if you want to just must multiply the number of each atom by its atomic mass to get the molecular mass).

Calculate the number of grams of O in that molecule:

O: 11 * 16.00 g/mol = 176.0 g of O.

Now use proportions:

176 g O / 342.30 g sucrose = x / 50.00 g sucrose

=> x = 50.00 g sucrose * 176.0 g O / 342.30 g sucrose =25.71 g O.

Answer: 25.17 g

What is the volume of a liquid with a density of 1.5 g/ml and a mass of of 78g ?

earnstyle [38]

D = m / V

1.5 = 78 / V

V = 78 / 1.5

V = 52 mL
