A laboratory instructor gives a sample of amino-acid powder to each of four students, I, II, III, and IV, and they weigh the sam

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 $AV_I_V=8.56g$

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: $\triangle_I = \frac{\triangle1+\triangle2+\triangle3}{3} = 0.107g$

Which contains more molecules: 1.00 mol, H2O2, 1.00 mol C2H2, or 1.00 mol CO?

xenn [34]

A mole of any chemical compound contains the same number of molecules - about 6.022 × 10²³ molecules.
So, 1 mole of H₂O₂, 1 mole of C₂H₂ and 1 mole of CO contain the same number of molecules.
