How many atoms of k are present in 195.49 grams of k? 3.0110 × 1024 6.0220 × 1024 1.1772 × 1026 4.5797 × 1027

Hello!

The answer is:

Why?

First, we need to look for the K molecular mass:

Also, we need to remember that 1 mol of a compound or element is equal to of that compound.

From the statement, we are asked to calculate how many atoms of K are present in 195,49 of K.

So, doing the calculations, we have:

So, we have atoms of K in 195,49 grams of K.

Have a nice day!

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
