In the mineral beryl [beal2(sio3)6] , what is the ratio of beryllium to aluminum to silicate (sio3) ? 1: 2: 6 3: 2: 1 6: 2: 1 1: 1: 1

The ratio of beryllium to aluminum to sillicate is 1:2:6

Explanation:

1. First write down the compound:

2. Then to know the ratio between them, write them down separately:

Beryllium: Be

Aluminum: Al

Silicate:

3. Write the quantity of each of them in the compound, that is the subscript:

Beryllium: Be = 1

Aluminum: Al = 2

Silicate: = 6

4. Therefore the ratio of beryllium to aluminum to sillicate is 1:2:6
