If 1.63 x 10^15 formula units of strontium chloride are needed to perform a chemical reaction, what mass would you need to measure out?

Lisa leaves her house and travels her route at a speed of 1.15m / s, at what time

Does it take to get to the bakery if you travel the same distance?

Explanation:

Given parameters:

Speed of Lisa  = 1.15m/s

Unknown:

Time taken  = ?

Solution;

To solve this problem, let us define speed.

Speed is the rate of change of distance with time. It is mathematically expressed as;

         Speed  =

Since the unknown in this problem is time;

                  time  =

Now input the value of the speed;

                  time  = s

Since the value of the distance covered is not given, it is impossible to solve any further
