A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable.
Balanced Equation: H2SO4 + 2NaOH --> 2H2O + Na2SO4
Moles= Mass/RMM
= 65.5/40
= 1.6375
Mole Ratio = 2:2
= 1.6375
Mass (H2O) = 1.64 x 18
= 29.5 g
Positive unless your mean to them then everyones negative towards you.
Answer:
The correct answer is 930 grams platelets.
Explanation:
The volume of blood given is 1.89 pints. Total number of gallons in 1.89 pints is,
= 1.89/8 = 0.236 gallon
1 gallon comprise = 3.785 L
So, 0.236 gallon comprise = 0.236 * 3.785 L = 0.89 L
As mentioned that 1 Liter of blood comprise 1.04 kilograms of platelets. Therefore, 0.89 L of blood will contain = 1.04 * 0.89 = 0.93 Kg platelets
1 Kg contain 1000 grams. So, number of platelets in grams will be,
= 1000 * 0.93 = 930 grams platelets.
Yes it need to be like that cause when it like that it like that
