FacebookTweetPin Determine the number of moles of hydrogen in 0.0885 mol C4H10 Solution: There are 10 atoms of hydrogen in every molecule of C4H10. Therefore, 1 mol of C4H10 will have 10 moles of hydrogen. 0.0885 mol C4H10 * (10 moles of hydrogen/ 1 mol of C4H10) = 0.885 moles of hydrogen LINKS General Chemistry…
FacebookTweetPin A sugar crystal contains approximately 1.8*1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Solution: To go from molecules to milligrams, we will first need to convert molecules to moles using Avogadro’s number, then convert moles to grams using Molar Mass of the molecule(C12H22O11) and finally convert grams to milligrams (1g=1000mg). LINKS General…
FacebookTweetPin The formula for density is Density =mass/volume We are given density and volume. Notice that the units for volume are mL and the units for density have mL as well which means we do not need to convert anything. We can now plug and chug 8.96 g/mL = mass/12.6 mL mass = 113 grams…
FacebookTweetPin In this reaction, alkene reacts with HX where X can be Br, Cl or I. To predict the product easily, you have to turn double bond into single and add X (Cl, Br or I) to the most substituted carbon from the double bond carbons. This follows Markovnikov’s Rule which states that halogen (or…
FacebookTweetPin Significant figures (sig figs) are used to indicate the precision of a measured number. Significant figures are the digits in a measured number that are known with certainty plus one last digit which is less certain. Rules For Significant Figures How many significant figures are in the following numbers? 786 1.20 2006 4.0500 0.4…
FacebookTweetPin Which of the following molecules can exist as Z or E isomers? Draw the (E) and (Z) forms. If one of the carbons on the C=C is attached to two same groups (such as two hydrogens), it can not have E/Z configuration. For example, if we look at the double bond in the top…
