States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

I keep getting this problem wrong because of the sig. digits, dont round till the end because if it is off by 0.1, it will be incorrect.
![### Problem Statement:
Aqueous hydrobromic acid (HBr) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide (NaBr) and liquid water (H2O).
Suppose 61.0 g of hydrobromic acid is mixed with 44.1 g of sodium hydroxide. Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
### Step-by-Step Solution Guide:
1. **Balanced Chemical Reaction:**
The chemical reaction can be represented as follows:
\[ \mathrm{HBr(aq) + NaOH(s) \rightarrow NaBr(aq) + H_2O(l)} \]
2. **Molecular Weights:**
- Hydrobromic acid (HBr): \( \approx 80.91 \, \text{g/mol} \)
- Sodium hydroxide (NaOH): \( \approx 40.00 \, \text{g/mol} \)
3. **Moles Calculation:**
- Moles of HBr: \(\frac{61.0 \, \text{g}}{80.91 \, \text{g/mol}} \approx 0.754 \, \text{mol}\)
- Moles of NaOH: \(\frac{44.1 \, \text{g}}{40.00 \, \text{g/mol}} \approx 1.103 \, \text{mol}\)
4. **Limiting Reactant Analysis:**
From the balanced equation, the molar ratio of HBr to NaOH is 1:1.
- Since \( 0.754 \) moles of HBr will react with \( 0.754 \) moles of NaOH.
5. **Excess Reactant Calculation:**
- Initial moles of NaOH: \( 1.103 \, \text{mol} \)
- Consumed moles of NaOH: \( 0.754 \, \text{mol} \)
- Excess moles of NaOH: \( 1.103 - 0.754 = 0.349 \, \text{mol} \)
- Excess mass of HBr: \( 0.349 \, \text{mol}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8269917f-e65a-4c61-8f6b-ddb45740edf7%2F1150ef14-1716-49dd-89e6-69489a25c61a%2F58gi2bn_processed.png&w=3840&q=75)
