Now, No. Hence, it is a stoichiometric mixture where there is no limiting agent. Hence, 0.5 mol of Na2CO3Na_{ 2 }CO_{ 3 }Na2​CO3​ is in 1 L of water or 53 g of Na2CO3Na_{ 2 }CO_{ 3 }Na2​CO3​ is in 1 L of water. (iv) 500.0 Therefore, 100 grams of CuSO4CuSO_{4}CuSO4​ will contain 63.5×100g159.5\frac{63.5\times 100g}{159.5}159.563.5×100g​ of Cu. = 6.023  ×  10236.023 \; \times \; 10^{ 23 }6.023×1023 atoms of carbon, Therefore, mass of 1 12 C _{}^{ 12 }\textrm{ C }12​ C  atom, = 12  g6.022  ×  1023\frac{ 12 \; g }{ 6.022 \; \times \; 10^{ 23 }}6.022×102312g​, = 1.993  ×  10−23g1.993 \; \times \; 10^{ -23 } g1.993×10−23g. With a focus on human cell biology and a problems-driven approach, the text explains the combinatorial architecture of biooligomers (genes, DNA, RNA, proteins, glycans, lipids, and terpenes) as the molecular engine for life. A sample of drinking water was found to be severely contaminated with chloroform, CHCl3, supposed to be carcinogenic in nature. Connect instantly with a live tutor online for 24/7 help. With a focus on human cell biology and a problems-driven approach, the text explains the combinatorial architecture of biooligomers (genes, DNA, RNA, proteins, glycans, lipids, and terpenes) as the molecular engine for life. The mass of O2 bear whole no. NCERT Solutions for Class 11 Chemistry: Chapter 1 (Some Basic Concepts of Chemistry) are provided in this page for the perusal of Class 11 Chemistry students. In three moles of ethane (C2H6), calculate the following: The subtopics covered under the chapter are listed below. Percent of Fe by mass = 69.9 % [As given above], Percent of O2 by mass = 30.1 % [As given above], = percent  of  iron  by  massAtomic  mass  of  iron\frac{percent\;of\;iron\;by\;mass}{Atomic\;mass\;of\;iron}Atomicmassofironpercentofironbymass​, = percent  of  oxygen  by  massAtomic  mass  of  oxygen\frac{percent\;of\;oxygen\;by\;mass}{Atomic\;mass\;of\;oxygen}Atomicmassofoxygenpercentofoxygenbymass​. The molecular formula of a compound can be obtained by multiplying n and the empirical formula.
