The AP Biology teacher is measuring out 638.0 g of dextrose (C6H12O6) for a lab the moles of dextrose is this equivalent to is 3.6888 moles.
<h3>What are moles?</h3>
A mole is described as 6.02214076 × 1023 of a few chemical unit, be it atoms, molecules, ions, or others. The mole is a handy unit to apply due to the tremendous variety of atoms, molecules, or others in any substance.
To calculate molar equivalents for every reagent, divide the moles of that reagent through the moles of the restricting reagent. The calculation is follows:
- 655/12 x 6 + 12+ 16 x 6
- = 655/ 180 = 3.6888 moles.

Answer:
Electrical energy = 130000000 J and Heat energy = 520000000 J
Explanation:
Multiply the amount of joules from the last question (650000000) by .20 and .80. (Which are the percentages)
The answer is B i know this because i just took it
Answer:
169.67Ω
Explanation:
This question is asking for the inductive reactance, which is calculated as follows:
X(L) = 2πfL
Where;
X(L) = inductive reactance (Ω)
f = frequency (Hz)
π = 3.142
L = inductance (Henry)
Given the information provided, f = 60Hz, L = 0.450H
X(L) = 2πfL
X(L) = 2 × 3.142 × 60 × 0.450
X(L) = 6.284 × 60 × 0.450
X(L) = 6.284 × 27
X(L) = 169.668
X(L) = 169.67Ω
