Concept Introduction:
Significant digits:
In a number, the digits which contribute to the precision of the number are said to be significant digits.
Rules for determination of significant digits in a number:
- All non-zero digits are significant.
- The zero’s appearing between two non-zero digits are significant.
- The zero’s before the non-zero numbers are not significant.
- Zero’s after non-zero number without decimal are non-significant.
- Zero’s after non-zero number with decimal are significant.
- Zero’s after the decimal point are significant.
- Any numbers with scientific notation are significant.

(B)1.88 kgCO2 express your answer in moles to three significant figures. (C) 48.8 g KNO3 express your answer in moles to three significant figures. (D) 116.2 kgNa2SO4 express your answer in moles to four significant figures.arrow_forward(a) The sodium ion did not take part in this chemical reaction(Diluted H2SO4(aq) versus NaOH(aq)). What do we call such an ion?(b) Draw a simple diagram which shows how the sodium ion mixes with water in solution.What do we call this physical process?arrow_forward
- Light travels in a vacuum at a speed of 3.00 × 108 m s-1 .(a) Convert this speed to miles per second.(b) Express this speed in furlongs per fortnight, a littleused unit of speed. (A furlong, a distance used in horse racing, is 660 ft; a fortnight is exactly 2 weeks.)arrow_forwardYou are given a hammer a battery, a bulb, wires and switch(a) How could you use them to distinguish between samples of metals and non metals?(b) Assess the usefulness of these tests to distinguish between metals and non-metalsarrow_forwardUse the meaning of the prefix "nano-" to select the value of "x" in this equation: 1 m = 1 x 10x nm . The value of " x " is (a) +9 (b) -6 (c) +6 (d) -9arrow_forward
- Suppose 25.4 grams of NaCl was added to 400 mL of water. The resulting solution was again diluted with water 1:100 with water. What is the final concentration of the NaCl in μM? The molecular weight of NaCl is 58.44.arrow_forwardA group of students took turns using a laboratory balanceto weigh the water contained in a beaker. The results theyreported were 111.42 g, 111.67 g, 111.21 g, 135.64 g,111.02 g, 111.29 g, and 111.42 g.(a) Should any of the data be excluded before the average is calculated?(b) From the remaining measurements, calculate the average value of the mass of the water in the beaker.(c) Calculate the standard deviation s and, from it, the 95% confidence limit.arrow_forwardMethanol (CH3OH) is a liquid at room temperature with a density of 7.91 ×102 kg/m3.In a certain experiment, from the reaction of 2.91 mL of methanol with 2.88 g of oxygen, 2.27 gof carbon dioxide was obtained.(a) What type(s) of chemical reaction is (are) occurring in this experiment?(b) What equipment do you think was used to measure the volume of methanol in thisexperiment?(c) Calculate the percent yield of the carbon dioxide in this experimentarrow_forward
