What represents 1 percent of the Earth's mass?
earths mass = 5.974 * 10^24 kg, so 1 percent = 5.974 * 10^22 kg
Which type of cell makes up 10 percent of the brain?
Brain cells :)
What percent of the mass of the isotope boron-10 are neutrons?
take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100
A compound having Bcc geometry has atomic mass 50 What is the density of the unit cell if its edge length is 290 pm?
Length of the edge , a = 290 pm =290 x 10-10 cm Volume of unit cell = ( 290 x 10-10 cm )3 = 24.39 x 10-24 cm3 Since it is bcc arrangement, Number of atoms in the unit cell, Z = 2 Atomic mass of the element = 50 Mass of the atom = atomic mass/ Avogadro number = M/No = 50/6.02 x 1023 Mass of the unit cell = Z x M/No = 2 x 50/6.02 x 1023 = 100/6.23 x 1023 Therefore , density = mass of unit cell / volume of unit cell = 100/6.023 x 1023 x 24.39 x 10-24 = 6.81 g cm-3
How much does the mass of the average human cell in kg weigh?
A typical cell mass is 1 nanogram, but all cells are different sizes and masses. For example, the largest known cell is that of an unfertilized ostrich egg cell. The smallest knwon independent cell is that of Nanoarchaeum equitans.
How you write in Microsoft Excel to make a number in cell A1 10 percent smaller than the number in D4 you enter?
=d4%10
What represents 1 percent of the Earth's mass?
earths mass = 5.974 * 10^24 kg, so 1 percent = 5.974 * 10^22 kg
What is the mass of an average cell?
3*10^(-11)
What happens when a bacterial cell is placed in 10 percent Nacl with penicillin?
The cell will plasmolyze.
How do you turn 10 percent into a fraction?
To make a fraction from any percent, divide the percent by 100. 10 percent = 10/100 or 1/10 .
How do you make 0.1 into a percent?
To make a decimal into a percent, just multiply by 100. 0.1*100 is 10. 0.1 is 10 percent.
What structure is 5-10 percent of the cell cycle?
mitosis
What happen to blood cell in 10 percent NaCL?
A 10% NaCl solution is hypertonic to a blood cell and would cause the cell to shrink, aka crenation.
What would happen if a cell containing 97 percent water were placed in a 10 percent salt solution?
Water would exit the cell causing the cell to shrink until an equilibrium is reached.
How do you make a number in cell A1 10 percent smallar than the cell in D4 in excel?
There are lots of ways you could do it. The formula in A1 could be any of these: =D4*0.9 =D4*90% =D4-(D4*10%) =D4-(D4*0.1)
Which type of cell makes up 10 percent of the brain?
Brain cells :)
What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
