Water's relatively small size allows it to fit between individual atoms, driving them apart. Water's hydrophobic nature separates polar and non-polar substances. Water's polarity allows it to dissolve ionic and polar compounds.
1 is hours and 2 is meters
Answer: Butane will effuse more quickly because it has a smaller molar mass
Explanation:
Molar mass of C4H10 = 58.123 g/mole
Molar mass of I2 = 253.808 g/mole
The number of moles of one substance given the amount in mass can be calculated by the use of the molar mass. This is the mass of a compound per 1 mol of the said substance. For, KCl the molar mass is 74.55 g/ mol
148 g / 74.55 g/mol = 2 mol KCl
Hope this answers the question. have a nice day.
