<h3>
Explanation:</h3>
<u>Step 1: Define</u>
1.204 × 10²⁴ molecules CH₃COOH
<u>Step 2: Identify Conversions</u>
Avogadro's Number
[PT] Molar Mass of C - 12.01 g/mol
[PT] Molar Mass of H - 1.01 g/mol
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of CH₃COOH - 12.01 + 3(1.01) + 12.01 + 16.00 + 16.00 + 1.01 = 60.06 g/mol
<u>Step 3: Convert</u>
- Set up:
![\displaystyle 1.204 \cdot 10^{24} \ molecules \ CH_3COOH(\frac{1 \ mol \ CH_3COOH}{6.022 \cdot 10^{23} \ molecules \ CH_3COOH})(\frac{60.06 \ g \ CH_3COOH}{1 \ mol \ CH_3COOH})](https://tex.z-dn.net/?f=%5Cdisplaystyle%201.204%20%5Ccdot%2010%5E%7B24%7D%20%5C%20molecules%20%5C%20CH_3COOH%28%5Cfrac%7B1%20%5C%20mol%20%5C%20CH_3COOH%7D%7B6.022%20%5Ccdot%2010%5E%7B23%7D%20%5C%20molecules%20%5C%20CH_3COOH%7D%29%28%5Cfrac%7B60.06%20%5C%20g%20%5C%20CH_3COOH%7D%7B1%20%5C%20mol%20%5C%20CH_3COOH%7D%29)
- Multiply/Divide:
![\displaystyle 120.08 \ g \ CH_3COOH](https://tex.z-dn.net/?f=%5Cdisplaystyle%20120.08%20%5C%20g%20%5C%20CH_3COOH)
<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 4 sig figs.</em>
120.08 g CH₃COOH ≈ 120.1 g CH₃COOH
Answer:
Packed inside the nucleus of every human cell are nearly 6 feet of DNA, which is divided into 46 individual molecules, one for each chromosome and each about 1.5 inches long. Packing all this material into a microscopic cell nucleus is an extraordinary feat of packaging.
Explanation:
Packed inside the nucleus of every human cell are nearly 6 feet of DNA, which is divided into 46 individual molecules, one for each chromosome and each about 1.5 inches long. Packing all this material into a microscopic cell nucleus is an extraordinary feat of packaging. For DNA to function, it can't be crammed into the nucleus like a ball of string. Instead, it is combined with proteins and organized into a precise, compact structure, a dense string-like fiber called chromatin.
