Answer:
Total we want 48 titanium to make 12.0moles
Answer:
89.7
Explanation:
First we have to look at the right of the digit which is going to be round. If it is 5 or greater than 5 than the number left to it should be increased by one.
For example
In given number 89.667 after three digits 8, 9, 6 the next digit is 6.
So in order to round the number to three digits 6 will rounded to 7 and value becomes 89.7
If the digit next to rounded digit is less than 5 than number will rounded as,
For example:
56.42
Rounded to three digit it will be 56.4.
