astraxan [27]

Answer:

3

Step-by-step explanation:

Explanation:

Although you have not been provided with direct masses, you can use the percentage composition values in place of masses.

First, calculate the number of moles of each element:

This is the formula for the ionic compound calcium carbonate, confirming that our result is indeed in the magnitude of a plausible answer. In fact, given the fact that calcium carbonate is ionic, it is also true that this empirical formula equates to the unit formula of the compound.

Janet has three coins.
tatyana61 [14]

Answer:

Janet has coins worth 252.5, 101, and 50.5.

Step-by-step explanation:

Let us call the three coins a,b, and c.

The first coin a is 5 times another coin<em> (let's say </em>b); therefore,

a = 5b,

and the third coin is 2 times the value of another coin<em> (it's coin </em>b<em>):</em>

<em />c =2b<em>.</em>

The total worth of all coins is 404; therefore,

a+b+c =404

or

5b+b+2b =404

8b =404

\boxed{b = 50.5}

with the value of b in hand, we find a and c:

a = 5b = 5(50.5)

\boxed{a = 252.5}

and for c:

c = 2 b = 2 (50.5)

\boxed{c = 101}

Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
