Answer:

1 mole of platinum

Explanation:

To obtain the number of mole(s) of platinum present, we need to determine the empirical formula for the compound.

The empirical formula for the compound can be obtained as follow:

Platinum (Pt) = 117.4 g

Carbon (C) = 28.91 g

Nitrogen (N) = 33.71 g

Divide by their molar mass

Pt = 117.4 / 195 = 0.602

C = 28.91 / 12 = 2.409

N = 33.71 / 14 = 2.408

Divide by the smallest

Pt = 0.602 / 0.602 = 1

C = 2.409 / 0.602 = 4

N = 2.408 / 0.602 = 4

The empirical formula for the compound is PtC₄N₄ => Pt(CN)₄

From the formula of the compound (i.e Pt(CN)₄), we can see clearly that the compound contains 1 mole of platinum.

Where does the Rand water get its raw water from?
TiliK225 [7]

The Rand water gets its raw water from canal connected with Vaal Dam and also from Vaal River Barrage Reservoir.

Explanation

Rand water is a purified water supplier system which supplies drinking water in South Africa.

It also provides purified water in industries and helps in sanitization of waste water.

The Rand water gets their source from waters in spruits or streams and then they purify it and supply to country like Gauteng province, Johannesburg and other parts of African continent.

It gets source water from canal connected with Vaal Dam and also from Vaal river barrage reservoir.

It is then purified by removing the suspended impurities and disinfecting the water and then supplied by pipelines to each homes.
