earths mass = 5.974 * 10^24 kg, so 1 percent = 5.974 * 10^22 kg

Yes, glucose can move into the cell through facilitated diffusion using glucose transport proteins on the cell membrane. The concentration gradient allows for passive transport of glucose molecules into the cell.
To make a 10 percent solution, you would need to dilute the 50 percent solution by adding 4 ml of solvent to 1 ml of the 50 percent solution. This will result in a total volume of 5 ml with a 10 percent concentration.
To prepare a 500g solution that is 10 percent sugar by mass, you need to calculate the mass of sugar required. Since 10% of 500g is 50g, you would weigh out 50g of sugar. Then, you would add enough water to the sugar to reach a total mass of 500g, which means adding 450g of water. Mix the sugar and water thoroughly until the sugar is fully dissolved.

The molar mass of benzene (C6H6) is 78.12 g/mol. To calculate the mass percent of benzene in a solution, divide the mass of benzene by the total mass of the solution, then multiply by 100. For example, if you have 10 g of benzene in a 100 g solution, the mass percent would be (10 g / 100 g) * 100 = 10%.
To make a fraction from any percent, divide the percent by 100. 10 percent = 10/100 or 1/10 .
To make a decimal into a percent, just multiply by 100. 0.1*100 is 10. 0.1 is 10 percent.

The mass of an average cell can vary widely depending on the cell type and size. However, most mammalian cells typically range from a few to 100 picograms (10^-12 grams).
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)

A home-using acetic acid solution is lesser than 10% w/w.
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.
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
10/(10 + 25) = 10/35 = about 28.6%
