A can of chicken broth contains 340 mg of sodium chloride in 286.7 g of broth. What is the percent by mass of sodium chloride in the broth?

0.12 & of NaCl

Explanation:

Determine the percentage of NaCl in the broth

First of all, we convert the mass from mg to g

340 mg . 1g/ 1000 mg = 0.340 g

Now  we can calculate the %

(0.340 g / 286.7 g) . 100 = 0.12 %

The percent by mass of sodium chloride in the broth is 0.118 %

Explanation:

Step 1: Data given

Mass of sodium chloride = 340 mg = 0.340 grams

Mass of broth = 286.7 grams

Step 2: Calculate the total mass

Total mass = mass of sodium chloride + mass of broth

Total mass = 0.340 grams + 286.7 grams

Total mass =287.04 grams

Step 3: Calculate percent by mass of sodium chloride

% mass NaCl = (mass NaCl / total mass) *100%

% mass NaCl = (0.340 grams / 287.04 grams) *100 %

% mass NaCl = 0.118 %

The percent by mass of sodium chloride in the broth is 0.118 %

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
