Answer:
The product of
and
is
. The reciprocal is
.
Step-by-step explanation:
We have to find the product of
and
before we find the reciprocal.
Before we do this though, we need to review a few words and their definitions.
First, the reciprocal of a fraction is when the numerator becomes denominator and the denominator becomes numerator.
Now we're ready to solve
:
Step 1: Use this rule:
.

Step 2: Simplify 7 × - 3 to - 21.

Step 3: Simplify 6 × 28 to 168.

Step 4: Move the negative sign to the left.

Step 5: Simplify
to
.

Now that we've found the product, we now must find the reciprocal.
Now using what we know and the process to find the reciprocal.
We can use that knowledge to find it:

Answer:
19 gram
Step-by-step explanation:
Formula of mass left after ionising:
where M is original mass and n is half lives.
Using the equation:
→ 18.75
Therefore, 18.75 g left after ionising.
∵ If rounded to nearest gram then 19 gram.
