Answer:
8.72 × 10^5 moles
Explanation:
To find the number of moles in 5.25 x 10^29 molecules of sucrose, we divide the number of molecules by Avagadro constant (6.02 × 10²³ molecules). That is;
no. of moles = no. of molecules ÷ 6.02 × 10²³ molecules
In this case of sucrose, no of moles contained is as follows;
5.25 × 10^29 ÷ 6.02 × 10²³
5.25/6.02 × 10^ (29-23)
0.872 × 10^6
= 8.72 × 10^5 moles

Answer:</h3>
= 633,600 Inches
<h3>
Explanation:</h3>
Speed refers to the rate of change in distance traveled by a body in motion.
It is the ratio of distance to time taken.
It is calculated by;
Speed = Distance ÷time taken
Therefore;
Distance = Speed × time
In this case;
Time taken = 12 minutes ( but 1 hr = 60 mins)
Thus, t = 0.2 hours
Speed = 50.0 miles/hour
Thus;
Distance = 50.0 miles/hr × 0.2 hours
= 10 miles
But, we are require to give the distance in inches;
1 mile = 63360 Inches
Therefore;
10 miles = 10 × 63360 Inches
= 633,600 Inches
If we compare a cell with an egg there is a major difference between the outer membrane
in case of cell they are bounded by semi permeable membrane
The semi permeable membrane is a selectively permeable membrane which allows the movement of only solvent molecule and not solute molecules through it.
So water can move into or out of the cell through cell membrane by a special physical process known as osmosis.
the water will move from a low concentration gradient to high concentration gradient.
