Table salt(sodium chloride or NaCl) is 40% sodium (Na) by weight. If a box of salt weights 26 ounces, how much Na is in the box of slat?
well, that would be 40% of 26, right?
0.40 * 26 = ____
To find out how much sodium (Na) is in the box of salt, we need to calculate 40% of the weight of the salt.
First, we calculate 40% of 26 ounces:
40% = 40/100 = 0.4 as a decimal
Na weight = 0.4 * 26 ounces
To find the weight of sodium, multiply 0.4 by 26:
Na weight = 0.4 * 26 ounces = 10.4 ounces
Therefore, there is approximately 10.4 ounces of sodium (Na) in the box of salt.
