What is the density of a cube that weighs 25.2 g and has dimensions of 2.56 cm by 3.71 cm by 8.30 cm?

So density is row(p)=M/V Lets calculate VV= 2.56 × 3.71 × 8.40 cm V= 79.78 cm^3 p= 25.2 g/ 79.78cm^3 p=0.32 I do quizzes and exams if your interested

The answer is a) carbon-12

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
