Answer: 19 grams

Explanation:

percent by mass = (mass of part)/(mass of whole) * 100

this means that in this question, 12 = x/160 * 100, where x is the amount of NaCl.

this means 12/100 = x/160, and thus x = (160)(12/100)=19.2 grams

The closest option is B.

Answer:

Second Option: 19 grams

Explanation:

Total solution weight: 160 grams

percent of NaCl in the solution: 12%

You take these two numbers and multiply them with 12 being over 100:

160 * \frac{12}{100} = 19.2 grams

and then just round to the nearest whole number: 19 grams

Is titanium a metal nonmetal or metalloid?
tatiyna
<span>Titanium is the first element in the fourth column of the periodic table. It is classified as a transition metal. Titanium atoms have 22 electrons and 22 protons. Titanium is fairly inactive and is very resistant to corrosion from other elements and substances like acids and oxygen. It has a relatively low electrical and thermal conductivity. Titanium is used to alloy with different metals such as iron, aluminum, and manganese where it helps to produce strong and lightweight alloys for use in spacecraft, naval ships, missiles, and as armor plating.</span>
