Answer:
<h2>Density = 1.67 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 50 g
volume = 30 mL
Substitute the values into the above formula and solve for the density
That's

Wr have the final answer as
<h3>Density = 1.67 g/mL</h3>
Hope this helps you
It describes how, when particles/mc/elements react, despite forming different substances the mass is neither created nor destroyed but only converted.
The atoms are constantly in motion
Answer:
B. gas state at room temperature
Explanation:
According to the calculation, set I is both the most accurate and most precise.
Exactness is a quality or state of being precise. 2a: comparison accuracy sense: the degree of precision with which an action is carried out or a measurement expressed 2b. The novel was fact-checked for historical authenticity. 2a: conformance to truth, to a standard, or to a model: exactness It is impossible to estimate the number of casualties with accuracy. Let's calculate the precision for the fourth set, considering
Δ1 = ∣(8.41−8.56)∣ g=0.15 g
Δ2 = (8.72−8.56) g=0.16 g
Δ3 = ∣(8.55−8.56)∣ g=0.01 g
Therefore:
