3g of NaCl of molecular weight 58.44g/mol is dissolved in 250g of water. What is the molarity of the solution?de

0.205M

What is the primary driver of protein folding?

The hydrophobic effect, or the tendency of nonpolar amino acid side chains to isolate themselves from the aqueous solution. As non polar amino acids are translated and come off the ribosome, they are surrounded by Clathrate cages, which are cages of water that protect the hydrophobic side chain from the aqueous solution. This increase in order of the water molecules is entropically unfavorable, so the cages eventually break and the nonpolar side chains are exposed to the aqueous solution. This causes the nonpolar side chains to fold inward to isolate themselves, thus forming the hydrophobic core of the protein and driving protein folding.

The sum of 3 times a number and 2 less than 4 times that same number is 61. Write an equation and solve to determine the value of the unknown number.

3n + 4n - 2 = 61 7n - 2 = 61 7n = 63 n = 9
