1. How many mEq of potassium are there in 750 mL of solution that has a K+ concentration of 58.65 mg/L? (Note: The molar mass of potassium, given in the periodic table, is 39.1 g/mol.) First, you need the total
. The prefix "milli-" indicates "1 thousandth," that is, the magnitude of 0.001 (see Resources). Hence, 1 mole is equal to 1 millimoles multiplied by 1,000. As an example, calculate concentration in millimolars if 0.5 grams of sodium hydroxide (NaOH) were dissolved in 500 ml of ...
所以,“scientific notation and 2 significant numbers”这句话意味着用科学计数法表示一个只有两个有效数字(即两位精度)的值。例如,0.00345可以写成3.5 x 10^-3(两个有效数字),而不是3.45 x 10^-3(三个有效数字)。
